T/CI 103-2022 Tri(1,3-dichloropropyl) phosphate used as flame retardant

Scope

Scope: This document specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of triphenyl phosphate (1,3-dichloropropyl) ester used as a flame retardant. This document applies to triphenyl phosphate (1,3-dichloropropyl) ester synthesized by catalytic reaction with phosphorus trichloride and epichlorohydrin as the main raw materials, which is primarily used as a flame retardant additive for rigid polyurethane foam materials such as polyurethane resins and epoxy resins. Main technical content: - Appearance: The appearance should be a colorless or light yellow transparent oily liquid. - Physical and chemical indicators should meet the requirements of Table 1. Table 1: Physical and chemical indicators Indicator Value Colorimetry/Hazen units (Platinum-cobalt number) 60 Triphenyl phosphate (1,3-dichloropropyl) ester content, % ≥90 Density (20°C), g/cm3 1.50±0.01 Water content, % ≤0.10 Acidity, mg KOH/g ≤0.10 Refractive index (n_D20) 1.498±0.03 Viscosity (25°C), mPa·s 1500–1900 **Test methods**: **Warning**: Users of this document should have practical experience in laboratory work.
